Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a crawler harvester. Background Art

[0002] In the existing agricultural machinery field, crawler harvesters are commonly used crop harvesting equipment, and their travel performance has a crucial impact on user operability during use. Because harvesters need to have multiple functions such as driving, power, travel, and harvesting, their structure is relatively complex. When the harvester harvests crops, the load on the harvester increases, which can easily affect the harvester's overall performance. In related technologies, the harvester's layout is not compact enough and the center of gravity distribution is not reasonable, which has a certain impact on the harvester's structural stability and travel stability.

[0003] Therefore, it is necessary to provide a crawler harvester to overcome the above-mentioned defectives. Utility Model Content

[0004] The purpose of the utility model is to provide a crawler harvester, which improves the problems of the harvester's insufficiently compact layout and uneven distribution of the center of gravity by rationally arranging key components in the overall machine solution.

[0005] According to one aspect of the present invention, a crawler harvester is provided, with the forward direction of the harvester as the front, comprising a cab, an engine assembly, a plunger pump assembly, a chassis, a crawler, a drive wheel, and a motor, wherein the engine assembly is placed under the seat of the cab, the plunger pump assembly is connected to the engine assembly by a plunger pump belt drive, the plunger pump assembly is placed in front of the engine assembly and is located below the foot pedal of the cab, the plunger pump assembly includes a first plunger pump and a second plunger pump arranged side by side on the left and right, the chassis is placed under the engine assembly for supporting the engine assembly and the plunger pump assembly, the crawler is placed under the chassis for realizing the walking of the harvester, the drive wheel is placed in the crawler and relatively close to the rear of the harvester for driving the crawler to work, the motor is connected to the drive wheel for driving the drive wheel to rotate, and the motor is placed in the crawler and relatively close to the rear of the harvester. This application helps to improve the compactness of the whole machine components, while providing more space for other functional mechanisms such as harvesting, threshing and cleaning, and also improves the problem of uneven distribution of the center of gravity of the whole machine, thereby improving the stability of the whole machine.

[0006] Preferably, the plunger pump assembly and the engine assembly are positioned on the same side of the plunger pump belt in the left-right direction. Furthermore, the plunger pump assembly and the engine assembly are positioned to the right of the plunger pump belt. This solution improves the utilization of the space below the cab and enhances structural compactness.

[0007] Preferably, the plunger pump assembly further comprises a spline sleeve connecting the first plunger pump and the second plunger pump, the first plunger pump is located on the right side of the second plunger pump, and the first plunger pump rotates synchronously with the second plunger pump.

The pulley can better transmit power from the engine assembly to the plunger pump assembly, while avoiding the plunger pump assembly and the engine assembly being directly arranged side by side, which would occupy a longer space in a single direction. This helps to improve the rational distribution of space on the chassis and facilitates the miniaturization of the entire machine.

[0009] Preferably, the crawler harvester also includes rollers positioned inside the crawler tracks, with the motor positioned behind the rollers. The rollers within the crawler tracks help support the tracks and facilitate their movement.

[0012] Preferably, the motor includes a left motor arranged in the left crawler and a right motor arranged in the right crawler. The above scheme can realize the driving of the left and right walking respectively, better realize the left turn and right turn operation, and help realize the flexibility of the harvester walking.

[0013] Preferably, the engine assembly includes an engine and an output pulley disposed on the left side of the engine and connected to the engine, wherein the output pulley is connected to the pulley via a belt transmission, which helps to transmit power.

[0014] Preferably, the plunger pump assembly further includes a transmission shaft connected to the second plunger pump, the transmission shaft being arranged in the left-right direction of the harvester, the right end of the transmission shaft being connected to the second plunger pump to drive the second plunger pump to rotate, and the left end of the transmission shaft being connected to a pulley, which is connected to the engine assembly via a belt to transmit power to the transmission shaft, thereby facilitating power transmission.
